I'm not sure how long this will be available, so take advantage ASAP.
Tesco Direct currently have this priced at £49.97 but you can get it down to £44.97 with the following code which gives you £5 off when spending over £30: TDX-SFFT
A £5 delivery charge shows at one stage during the checkout process but this is fully discounted (removed) before placing the order.
